What is the treatment for coronary artery disease?

• A. Stent
• B. ACE inhibitor
• C. Angioplasty, lifestyle changes
• D. Pacemaker

Answer: (C)

Treating coronary artery disease focuses on restoring blood flow to the heart and lowering ongoing risk factors that worsen artery blockage. Angioplasty is a procedure that opens a narrowed coronary artery, often with a stent to keep it from closing again. Combining this revascularization with lifestyle changes helps both to relieve symptoms and to prevent further plaque buildup—dietary improvements, regular exercise, quitting smoking, and controlling blood pressure, cholesterol, and diabetes.

ACE inhibitors can help manage blood pressure and reduce heart strain, but they don’t directly open blocked arteries. A pacemaker addresses rhythm problems, not the arterial block. A stent is part of the angioplasty procedure, but the best overall treatment choice includes both opening the artery and changing risk factors, which is why angioplasty with lifestyle changes is the most appropriate answer.
